I´m planning to pump a 1.3L chamber, but, as you can see at the link above, everybody says, that filling a 1.3L with a shock pump is almost impossible... And a 400psi pump, is awesome... I jus...

Suspension Shock Pump.

I got some problems to fill up my 1.3L chamber to about 250psi. I bought a cheap deutch floor pump and it failed at 100psi, and now, I can´t even pump until 20psi. So I was looking for some "high pressure" pump, and I found some Suspension Shock Pump rated 400psi. It is used to fill bike air suspens...

The guy collected a lot of documents about Survival Techniques, and a lot of information about guns, field man...

@far_cry: Do you think that a ~7mm, constricts much flow? Running at aprox. 100psi, using a 1/2" pipe and a 3/4" as barrel... Fire extinguisher as chamber (1.125liters), and piloted by a 1/2" BV.

@far_cry: Can you tell me the inner diam. of you barrel port? I have found where is my error, as stated by BTB: I think there is no-or not enough difference in diameter between the sealing face surface and the crosssection of the piston itself. IOW, the pressure has no surface to push against.. The ...

@le_rufus: Yeah, I´m filling throught the ball valve side. To be correct, through the schrader valve. I got the dimensions... Here you are: http://img148.imageshack.us/img148/1411/pistonhousing.th.jpg And I realize, that, my piston MUST be around 2,10cm, and my sealing face around 2,40cm (inner diam...

@Jrrdw - Yes it seal... I tried a different shapes (flat, rounded and "conic). And none releases air throught the barrel side, just throught the BV. If I push the piston using my finger (low pressure 15psi), the piston slides back and some air goes throught the barrel. Blowing air throught the BV, t...

@jrrdw - Theres no piston in the picture... I guess what you see is the "Barrel", like this fitting:

I screw this fitting, into the Tee (so I have interchangeable barrel).

Piston - Dont Release Air.

Hi, I have a problem with my piston. It seals perfectly (Barrel Sealer). But when I open t he BV (Exhaust) it dont seat back, so, all the air goes throught the BV instead of barrel. Tried a lot of pressures (20psi or 150psi), even blowing air throught the BV (the piston seals the barrel), but when I...

@hubb017 - Yes thats the only difference I guess... The spring thats shuts the outlet air... Presta valves, the valve shuts from the outlet pressure, more pressure, more tight close... I check everywhere for threaded schrader valves... But I just found the "flat" ones... BCArms offline... * I live i...
